The costs of replacing coal plant jobs with local instead of distant wind and solar jobs across the United States.

To further a just energy transition, jobs lost at retiring coal plants could be replaced by jobs at wind and solar plants. No research quantifies the feasibility and costs of such an undertaking across the United States. Complicating such an undertaking are workers' place-based preferences that could prevent them from moving long distances, e.

Dynamic DNA material with emergent locomotion behavior powered by artificial metabolism.

Metabolism is a key process that makes life alive-the combination of anabolism and catabolism sustains life by a continuous flux of matter and energy. In other words, the materials comprising life are synthesized, assembled, dissipated, and decomposed autonomously in a controlled, hierarchical manner using biological processes. Although some biological approaches for creating dynamic materials have been reported, the construction of such materials by mimicking metabolism from scratch based on bioengineering has not yet been achieved.
